python 整合linux命令搜索
今天需要在指定目录下搜索文件内容，没有早到合适命令，顺便学习了getopt的使用。#!/usr/bin/pythonimport sysimport osimport getoptdef usage(): print '''Help Information: find "path" | textsearch.py -w "findstring" -h: Show help information -xValue: ...'''findWord = ""try: opts,args=getopt.getopt(sys.argv,'w:h') #print opts #print args for o,value in opts: if o=='-h': usage() if o=='-w': findWord = value.strip()except getopt.GetoptError,err: print str(err) usage() sys.exit(0)if len(findWord) ==0: usage() sys.exit(0)#for i in range(200):i = 0while True: lineStr = sys.stdin.readline() if lineStr == None or len(lineStr)==0: break else: #print i,lineStr.strip() os.system("grep -n -H \""+findWord+"\" " + lineStr) #system( command) i+=1
使用方法如下：
find path | wordsearch.py -w "search word"
